For several years, most news articles about a computer, network, or Internet-based compromise have mentioned the phrase "zero day exploit" or "zero day attack," but rarely do these articles define what this is. A zero day exploit is any attack that was previously unknown to the target or security experts in general. Many believe that the term refers to attacks that were just released into the wild or developed by hackers in the current calendar day. This is generally not the case. The "zero day" component of the term refers to the lack of prior knowledge about the attack, highlighting the idea that the victim has zero day's notice of an attack. The main feature of a zero day attack is that since it is an unknown attack, there are no specific defenses or filters for it. Thus, a wide number of targets are vulnerable to the exploit.

The novel coronavirus has changed many aspects of life for millions of people globally, including where they work. With the increase in remote work, it is important for both individuals and companies to be aware of the added cybersecurity risks. Join us as Paula shares real world examples and tips on how we all can be better prepared.

For women in IT, advancing your career can be a challenge in itself. In the Global Knowledge 2019 IT Skills and Salary Report, only eight percent of senior- and executive-level IT professionals are women. We have pulled data from our research that sheds light on the job roles, skills, challenges, certifications and experience of women in tech who have progressed to the highest levels of an organization.

Does your company have a risk management program? In this hour-long webinar, cybersecurity expert and Global Knowledge instructor David Willson will explain why you should. In light of recent breaches at Target, Nieman Marcus, Michaels, Yahoo, and a growing list of others, we're learning that FBI Director Mueller was right when he said getting breached is not a matter of if, but when. While having a risk management program may not prevent a breach, it can certainly lower the risk of one, ensure compliance, and reduce or even eliminate your liability if a breach does occur, enabling you to recover quickly and to protect your reputation. Beyond explaining the importance of a risk management program, David will tell you how to implement one, including conducting a basic risk assessment, policies you'll need, and training your workforce.

Watch this recorded webinar as CompTIA’s chief technology evangelist and Global Knowledge’s federal sales director discuss how pentesting has morphed.

This year, CISSP-certified IT professionals have the third highest global salary ($116,573) and the 10th highest in North America ($123,815). This is nothing new—CISSP has ranked in the top 10 in the U.S. each year since 2015, even coming in first in 2018. CISSP is a top-paying certification year after year. But how has it remained so relevant and valuable?

One of the main weapons of organized crime on the Internet is the use of junk email, also called spam. Hackers use spam for a number of purposes such as selling counterfeit products (medicines, particularly) to steal your personal or financial information, or to infect your computer with spyware and malware. This malicious software can then hijack your computer and your Internet connection to help propagate itself.

“Twisted Pair” is another way to identify a network cabling solution that’s also called Unshielded Twisted Pair (UTP) and was invented by Alexander Graham Bell in 1881. Indoor business telephone applications use them in 25-pair bundles. In homes, they were down to four wires, but in networking we use them in 8-wire cables. By twisting the pairs at different rates (twists per foot), cable manufacturers can reduce the electromagnetic pulses coming from the cable while improving the cable’s ability to reject common electronic noise from the environment.

The Cisco UCS is truly a “unified” architecture that integrates three major datacenter technologies into a single, coherent system: Computing Network Storage Instead of being simply the next generation of blade servers, the Cisco UCS is an innova­tive architecture designed from scratch to be highly scalable, efficient, and powerful with one-third less infrastructure than traditional blade servers.

That depends on their configurations. For example: While it makes very good sense to include redundant physical links in a network, connecting switches in loops, without taking the appropriate measures, will cause havoc on a network. Without the correct measures, a switch floods broadcast frames out all of its ports, causing serious problems for the network devices. The main problem is a broadcast storm where broadcast frames are flooded through every switch until all available bandwidth is used and all network devices have more inbound frames than they can process.
